Multiple UHECR Events from Galactic hadron jets

We propose a new observational test of top-down source models for the ultra-high-energy cosmic-rays (UHECRs), based on the simultaneous observation of two or more photons from the same Galactic hadron jet. We derive a general formula allowing one to calculate the probability of detecting such ‘multiple events’, for any particular top-down model, once the physical parameters of the associated ha...

Studies of the UHECR propagation in the Galactic Magnetic Field

We present the results of simulations of the ultra-high energy cosmic ray (UHECR) propagation in the Galactic magnetic field (GMF). Different assumptions on the large-scale GMF structure and/or primary particle lead to distinctly different deflection patterns of the highest energy cosmic rays (CR). The GMF modifies the exposure of an UHECR experiment to the extragalactic sky. We estimated these...

Magnetic horizons of UHECR sources and the GZK feature

We study the effect of random extra-galactic magnetic fields on the propagation of protons of energy larger than 10 eV. We show that for reasonable field values (in the 100 nG range) the transition between diffusive and ballistic regimes occurs in the same energy range as the GZK cutoff (a few 10 eV). The usual interpretation of the flux reduction above the GZK energy in terms of a sudden reduc...

Galactic Superluminal Sources

A new class of X-ray sources was clearly established with the discovery of highly relativistic radio jets from the galactic sources GRS 1915+105 and GRO J1655-40. Both of these objects have given us a broader view of black holes and the formation of jets, yet they also show the complexity of the accretion environment near relativistic objects. The fast apparent motion of the jets, their luminos...

Galactic Distribution of Chirality Sources

Biochemical processes are known to utilize only one enantiomer, e.g. amino acids used by terrestrial life are generally the left-handed version. The concepts of chirality, optical activity and chiral enrichment are explored in the context of the origin of life in the universe before Earth. Chirality as a feature of terrestrial life suggests neither a special place for local development of homoc...
